Umbhobho ocwangcisiweyo phantsi kolu luhlu uya kulungeleka ukugoba, ukujiya, kunye nemisebenzi efanayo yokubumba, kunye ne-welding.Xa intsimbi kufuneka idityaniswe, kucingelwa ukuba inkqubo ye-welding efanelekileyo kwinqanaba lentsimbi kunye nokusetyenziswa okujoliswe kuyo okanye inkonzo iya kusetyenziswa.
I-API 5L GR.B Umbhobho wentsimbi obunzima obunzima bodonga lwenziwa ngokutsalwa ngokubanda okanye ngokuqengqeleka kushushu, njengoko kufunwa ngabathengi.

Amanqaku:
1. Ukunyamezelwa kobunzima busebenza kubunzima obubaliweyo bombhobho odibeneyo kunye nokudibanisa kunye nobunzima obufakwe kwitheyibhile okanye obaliweyo kumbhobho ocacileyo.Apho ukunyamezelwa kobunzima bodonga olubi oluncinci kunezo zidweliswe ngasentla kwitheyibhile echazwe ngumthengi, ukunyamezela ubunzima bokudibanisa kubude obunye kuya kwandiswa ukuya kuma-22.5 epesenti ngaphantsi kobunzima be-wail ukunyamezela okubi.
2. Umthwalo wemoto owenziwe ngombhobho ovela kwizinto ezingaphezulu kweyodwa, ukunyanzeliswa kweemoto kufuneka kusetyenziswe kwisiseko somyalelo ngamnye.
3. Ukunyamezela kwezinto ze-odolo kusebenza kubuninzi bebonke bombhobho othunyelwe kwi-odolo ye-oda.
